Kidney Cancer: Tests After Diagnosis
What tests might I have after being diagnosed?
After a diagnosis of kidney cancer, you'll likely need other tests. These imaging
tests help your healthcare providers learn more about your overall health and the
cancer. They can help show if the cancer has grown into nearby areas or spread to
other parts of your body. The test results help your healthcare providers decide the
best ways to treat the cancer. If you have any questions about these or other tests,
be sure to talk with your healthcare team.
The tests you have may include:
Imaging tests
Chest X-ray
A chest X-ray is done to look for changes in your lungs. These might be a sign that
the kidney cancer has spread to your lungs or chest. An X-ray uses a small amount
of radiation to make an image of organs and bones inside your body. It can show enlarged
lymph nodes in your chest.
Abdominal ultrasound
Ultrasound uses sound waves to create images of your insides. For this test, a gel
is put on your belly and a small wand called a transducer is pressed on your skin
to look at your abdominal organs (those inside your belly). The transducer gives off
sound waves and picks up the echoes as they bounce off the tissues. A computer makes
these echoes into images. This test can be used to help figure out if the cancer has
spread from your kidneys to other organs, such as the liver.
Bone scan
This test may be done if your healthcare provider thinks the cancer might have spread
to your bones. A small amount of a radioactive substance is put into a vein in your
hand or arm. It travels through your blood and collects in bones where there is damage.
Then the scan is done to show these areas. The damage may be from cancer or other
things, like arthritis. More testing may be needed to find the exact cause of the
bone changes.
Renal angiogram
This is a type of X-ray that uses a contrast substance to get pictures of the blood
vessels that are taking blood to the kidney tumor. The contrast is put into the artery
that leads into your kidney. X-rays are then taken to map the flow of the contrast.
This test helps healthcare providers plan surgery to take out the tumor. Angiography
of the kidney blood vessels is often done as part of a CT or MRI scan.
CT scan
A CT scan uses a series of X-rays and a computer to make detailed 3-D pictures of
the inside of your body. You may need to drink a contrast substance (contrast dye)
or it may be put into your blood through a vein. The contrast helps show more details.
You may have a CT scan of your chest, abdomen, or pelvis.
MRI
An MRI uses large and strong magnets, radio waves, and a computer to make detailed
pictures of the inside of your body. A contrast substance called gadolinium may be
put into a vein to help show details clearly. MRI might be done if you can't have
a CT scan. It's also very good at showing whether the cancer has grown into major
blood vessels, the brain, or spinal cord.
Working with your healthcare provider
Your healthcare provider will talk with you about which tests you'll have. Make sure
to prepare for the tests as instructed. Tell your healthcare provider if you had allergic
reactions to contrast before. Ask questions and talk about any concerns you have.
